general is well ImwntO thOSQ'SkiHea the art. Thatmuc'hof the National machine herein illustrated, comprises aFb'ed plate 10 supported byuprig'ht sides1111. T he sides 11 11 extend above the bed plate and form bearings 12 12 fortheuprightrods 13 13 of a vertically movable driving head 14 con necting the upper "ends of the rods. The rods are pro-videdwith collars 15 and helical springs lfiwhiclilserve to normally hold the:

rods and driving head in an elevated posi tion. 'Th'e'rods andldriving head areadapt the rods and the driving head 14. The work or shoe which is toreceive a heel is sup- {ported on a-suitable'jack located on the bed plate "10 beneath thedriving head 14.

The forinofwork rest, herein illustrated and indicated by thenumeral20, is mounted on anupright po'st 21 which is adjustably supported in-a socket 22. The base of the socket has parallel flanges 23 23 which are 5 adapted to slide in guides 24 24 secured upon theb'ed plate10, and extending from front to rear thereof. 'The jack by reasonof its mounting is adapted to be manually moved to operative or attaching'position directly '90 tion, as shown in Figs. 2 and '3, in which a shoe maybe morereadily put on or takenunder the driving head, or to a forward posioff. The bed plate 10 is also provided with a work gage which is adapted to cooperate withthe ack in holding a shoe inoperative position. The work gage and inafter described in detail. 4 I Referringto Figs. 2, 5, 8 and 10, it will be seen that the driving head His provided with a bracket or arm 25 extending from the jack arehererear thereof. Thearm 25 is provided with p a'bearing for a vertical rotary shaft 26 to thelowejr end of which is aflixed a carriage i 27 having a plurality of radial arms or bosses 28. The numberof arms 28 shown inthis" form of the invention is four and each is adapted to support an independently I rotatable carrier adapted to carry either loaded heel or a heel lift." Although there are four carriers illustrated uponthe draw- 11o riers may be provided without departing from the scope of the invention. The carriers are arranged on the carriage in a cir-, cular series so that when the carriage is rotated, as hereinafter explained, the carriers are moved successively into operativeposition relatively, to the driving head, and

then away from operative position to a posi-' tion in which it is more convenient to supply to the carriers the loaded heels and heel lifts. The carriage 27 is rotated step-by-step and its rotation is interrupted whenever a carrier moves to operativeposition under the main body of the driving head. As the car riage 27 rotates step by step, the carriers move from operative position under the driving head toward the rear, of the machine each carrier stopping in its rotation three times before completing a rotation about the axis ofthe carriage, and'it is during one or more of these pauses that the carriers are in position to receivethe heels and lifts.

The reciprocation of the driving head l4 is utilized to eifect the step-by-step rotation of the carriage 27 by means of mechani sm which causes the carriage to move-during the upward stroke of the driving head and to remain stationary relatively to the head during the downward stroke of the latter;-

The upper end of the shaft 26 is provided with a bevel gear 29 afiixed to the shaft by a set screw 30. The gear 29 intermeshes with a bevel gear 31 likewise ailixed to a shaft 32 extending. from front to rear through bearings in the driving head, and having on its front end, a toothed clutch member 33. The member 33 is adapted to cooperate with an annular toothed clutch member 34 affixed to a spur gear 35 loosely mounted on the shaft 32 between the member 33 and the driving head. The gear 35 intermeshes with an idle gear 36 mounted upon a stud 37 projecting forwardly from the driving head. The gear36 also intermeshes with a stationary toothed rack 38 affixed to an arm or bracket 39 projecting upwardly from one of the side membersll. As the driving head moves up and down relatively to the rack 38, the latter causes oscillation of the gear 35, the latter being free to turn about the shaft 32 as previously stated. The clutch member 34 is of the ratchettype and adapted to turn the clutch member 33 in one direction only, and for this reason, the member 33 is adapted to move longitudinally on the shaft 32 so as to permit the member 34 to turn in one direction withoutturning the member 33. The latter clutch member is splined to the shaft 32 by keys .40, and it is forced against the member 34 bymeans of springs 41 contained in sockets formed in the member 33,-and abutting against a washer'42 affixed to the when viewed from the front.

forward end ofthe shaft. The inclination of the teeth of the clutch members is such as to impart a clockwise rotation to the shaft 32, and consequently rotation of the 'carriage 27 such as to cause the carriers thereon to move from right to left of the machine As hereinbefore stated, the carriage 27 in this embodiment of the invention is provided with four carriers and for this reason, the clutch members 33 34 are provided eachwith four equallyspaced teeth. The range of reciprocatory movement of the driving head together with the relative size of the gear 35, is such as to cause the said gear to oscillate through an arc of'slig'htly more than 90 of a circle. It may be seen therefore that the oscillation of the clutch member 34 is such as to cause. it to rotate the clutch member 33 step by step, each step being just 90 of a revolution. The gears 29 and 31 being carriage 27 a step-by-step rotation corresponding exactly with that of the shaft 32, and consequently the carriage pauses in its rotation as the carriers thereon'are moved successively into operative position.

The carriers, hereinbefore referred to, comprise two heel carriers 43 43 and two heel-lift carriers 44 44. The heel carriers 43 are located at diametrically opposite points on the carriage 27 and the heel-lift carriers are. likewise located at diametrically opposite points between the carriers 43. Bymeans of this arrangement, the carriers form a circular series, of which the alternate members are heel carriers, and the intervening members heel-lift carriers. therefore follows that, as the carriage is rotated step by step, first a heel carrier is brought into operative position relatively to the head nd then a heel-lift carrier is brought intooperative position. In detail, each heel carrier comprises a rectangular block 45 having acylindrical portion 46 bearing in a socket in the arm 28 of the carriage, and a cylindrical stem 47 having a bearing in a hub 48 of the carriage. The blocks 45 are adapted by reason of their bearing in the carriage to rotate relatively thereto, each -on an axis extending radially of'thecarriage. The cylindrical portion 46- e of the block is provided with an annular peto the driver plate 52 and projecting down- Wardly therefrom. The heel carrier plate 43 is aflixed to one end of a stud 55 which extends through the stem of the driver plate into the socket 51. The inner end of the stud 55 is provided with a washer 56 secured in place by a nut. y

57 is a helical spring contained in the socket 51 and compressed between the end 'wall of the socket andthe washer'56. The

spring 57 normally forces the washer against the inner end'of the driver'plate stem thereby normally holding the heel carrier plate 43 away from the driver plate 52. v The plate 43 is providedwith apertures 58 which regall times inclose the lower ends of the drivers. The heel carrier is adapted to receive a loaded heel when it is diametrically opposite the position it occupies when it is in po sition to attach a heel.

Referring to Fig. 8, the heel carrier shown in section is in operative or attaching position, and the carrier shown in elevation. is in receiving position at adiametrically opposite point. [A heel a adapted to be attached by this machine, is previously loaded with nails 5 .whose heads project a suitable distance therefrom. The heel is preferably placed upon the heel carrier when the latter is at rest ina position nearest the rear of the machine, as shown in Figs. 2, 3 and 8. In Fig.

2, a heel is shown directly above the heel carrier which is to receive it, the nails in the heel and the apertures 58 in the heel carrier being correspondingly arranged so as to register one with the other. The nails inserted in the heel all have some slight inclination 'one to another, and by reason of this inclination, the nails when they are inserted in the apertures 58, bind sufficiently therein to firmly hold the heel regardless of whatever position the carrier may assume.

As an ad ditional means for holding the heel more firmly in position on the carrier, the latter is provided with a spring plate 59 having a series of teeth 60 adapted to engage the side of the heel. One end of the plate 59 is afiixed to the driver plate 52, 'and'the otherend of, the plate 59 projects beyond the carrier so that it may be grasped and sprung so as to displace the row of teeth60,

which is approximately-midway between the ends of the plate-59 s'ufiiciently to permit the application of the heel. When the plate 59 is released, the teeth 60 spring toward the heel and hold it in place.

It will beobservedthat theheelcarrier in receiving position stands with its carrier plate 43 approximately uppermost, and that the carrier which lies directly under the driving head in driving position is turned so that the carrier plate 43 is at thebottom. with its heel dependingtherefrom; The lat ter position is necessary in order to-attach a its individual axis to-the first describedpo heels to the empty carriers may see the aper- Eachcarrier isprovided with a gear 61 with a stationary gear 62 aflixed :to the bracket-25 of the head.

The dove-tail connection between the plate69 and the block 65 is adapted to permit the formerto be moved relatively tothe latter in aline transverse to the axis of the block, 'while the dovetail connection bethe movementof the plate 69, or parallel to the axis of the block 65.

The movable lip 73 is adapted to engage the breast or straight edge of the'lift and to press the rearor against the lips 7 2.

The inner end of the'pin 75 is 'connecteditoto cause the lip 73 to cooperate with the lips 72 to frictionally hold a lift as explained.

Referring again to Fig. 10 in which the relative positions of the planetary gears are shown at A, B, C, D, it will be seen that all of these gears occupy the different positions successively as the carriage 27 is actuated. The planetary gear 66, belonging to one of theheel-lift carriers, is shown at position A, in which position the carrier is adapted to receive a lift. This position of the lift carrier is also shown in Figs. 1, ,3, and 5. The lift carrier is here atthe left side of the machine.

The gear61 belonging to one of the heel carriers and shown in position B in Fig. 10 indicates the position of the heel, carrier when it is adapted to receive a heel. :This

position of the heel carrier is shown in Figs. 2, 3, 5 and 8, and the heel carrier is at the rear of the machine. The gear 67 belonging to the other lift carrier and shown at position C in F ig. 10, indicates the position at which the lift carrier pauses on its approach to operative or attaching position. The gear '61 belonging to the other heel carrier and shown in position D in Fig-10, indicates the operative or attaching position of the heel carrier. This position ofthe heel carrier is shown in Figs. 1, 2, 5 and 8. A carrier after having attached either its heel or its lift, as the case may he, moves from position D to A causing its planetary gear to engage the series of teeth 63 on the gear 62. The numseries of teeth and theseries of teethfit.

her of teeth 63 relative to the number of teeth on the planetary gear is such as to impart to the latter a rotation of slightly less than 180. During the next step in the rotation of the carriage in which the planetary gear moves from position A to position B, the said gear leaves the series of teeth 63 and passes over a blank space between that During this movement, the position of the planetary gear relatively to its own aXis remains unchanged. As the planetary gear.

movesfrom position B to position C, it engages the series of teeth 6A which impart to the said gear another partial rotation of slightly less than 180. Another blank space separates the teeth otand teeth 63 between positions O and D, and inasmuch as the planetary gear whose movement is being described, has so far received two partial rotations, each slightly less than 180, it is clear that some means must be provided to impart additional rotary movement to the gear and.

its carrier sufficient to complete one revolutionabout their individual axes, in order to edges of the carriers which lie above the horizontal plane of the under face 7 9 of the driving head. Each carrier as it approaches operative position relatively to the driving head, engages the plate 78 and is rocked thereby about its axis so that its top face assumes a horizontal position as it passes under the driving head. A revolution of the carrier about its axis is therefore completed, and its plane relatively to the plane of the under face 7 9 of the head is such that it engages the said face when in operative position. Subsequent downward movement of the head therefore exerts pressure directly upon the carrier which'lies beneath it and no undue strain is imposed upon the carriage or other carriers when the operative carriage is attaching its heel or lift.

When a heel a is supported by a carrier as shown in Fig. 8, with the heads of the nails occupying the apertures 58 in the carrier plate 43, the ends of the nails are adapted to abutagainst the ends of the drivers 54:. With a shoe 0 supported in operative position upon the work rest beneath the driving head, the latter attaches the heel to the shoe by descending bodily together with the carriage 27 and all the parts mounted thereon. The heel engages the heel seat of a shoe just an instant before the driving head reaches the lower extreme of its movement, and

while the downward movement of the heel is arrested by contact with the shoe,the driving head continues to move a short distance toward the shoe thereby causing the driver from the plate 52. This latter movement of T the driver plate 52 causes the drivers 54: to advance through the. apertures'58 and to drive thenails through the heel and into the heelseat of the shoe,'leaving the heads of the nails a short distance above the surface of the heel for the purpose of subsequently receiving a heel lift. When the driving head l tstarts on its upward movement and moves far enough to raise the carrier plate 43 above the protruding heads ofthe nails, the clutch members 33 and 34, hereinbefore described, cooperate with each other to ad- Vance the carriage 27 another step in its rotation. As the heel carrier, whose operation has just been described, leaves its operative position under the driving head, a heel-lift carrier moves under the driving head with 7 The heel lift clamps 72 73' by reason of their gentle frictional contact with the lift* leave the latter onthe heel without'any appreciabletendency to pull it awayfrom the nail heads.

been described, assume the positions indie cated in Fig. 10 by B and A respectively. These two carriers are therefore in "position to receive another loaded heel and another lift, While their diametrically opposite mates" are in position to attach their heel and lift with'which they are presumably provided. It'will be observed that when the heel carriers are in operative position, their spring clamps lie on the side toward the direction in whichthe carriage rotates, so that when a heel carrier advances after having attached a heel, its clamp moves away from the heel and becomes disengaged therefrom without interfering with the heel which; v

into a depression 84 formed in the shoulder 83. The depression 84 is so located with relation to the block that it registers with and receives the end of the pin 80 when it is moved to position A. The end of the pin 80 remains in the depression 84 from the time its carrier arrives at position A until it leaves position BL The teeth 64 on theggear 62then impart additional rotationto the carrier as previously described,'and the pin 80 is forced. back into its pocket 81 by the advancing of the depression in the shoulder 83,-and the carrier is then securely held by the engagement of its planetary gear with the teeth 64. a j It has been hereinbefore explained how the clutch member 34 drives the clutch member 33 and shaft 32 in one'direction'jonly, and it is therefore "preferable that some means he provided toprevent the member 33 and the said shaft from undue rotation stroke, and to prevent theshaft 32 from being unduly rotated in the direction in which .70

For this purpose, the disk ispro vided with fourtapered holes 87'or one-for each step of movement in a revolution of the carriage 27. The holes 87 are adapted to successively receive the, tapered end of a pin or bolt 88 =mounted in a bearing on the head and adaptedto slide in and out toward and fromjthe disk. "The other end oflthe pin 88 is pivotally con- \85 7 nected to the free end of an arm 89 which is affixed to one end of a rock shaft90 also mounted in hearings on the head. The

other end of the rockshaft 9O is provided of the rock shaft next to the arm 91. The

arm 95is free to turn about the rock shaft 7 and'itis connected with 'the armf9l by a spring 96. This spring servestwopurposes is of which one is to normally hold the arm 91 so as to effect the insertion oftheibolt' 88 into one of the holes in the disk 85. The

other purpose of the spring 96 "is to hold the free end of .theiarms95 against a pin 97 pro truding from the plate 93 as shown in Fig. 2. The 'plate 93 is provided with slots 98 through which the bolts 94 extend to secure the plate to the frameofthemachine and by reason of these slots, theplateis capable i of a' slight vertical movement relatively to the fiameyWhen the driving head des 'scends, the arm 91 engages the upper-end of the projection 92 and is moved thereby so as to oscillate the rock shaft and so to cause the arm 89 togwithdraw the bolt 88 from the hole which it occupiesin'the'disk 85. The arm 95 at the same time, descends with the driving head, being heldaga'inst the pin 97by meansof the 'sprin-g96 as already stated. j p t 99 is a depression formed in the edge of the'a'rm 95 which engages thepin 97 and it is adapted to register with the pin when the driving head is at its lowest position as indicated in Fig.5. A shoulder 100 of the depression 99 then underlies the pin'97 and engages the same when the arm 95 subsequently. rises v with the driving head. This shoulder engaging the under side of the pin 97 causes the pin and the' plate 93 to rise a short-distance with-the drivinghead thereby holding the arm 91in the position gage the shoulder100 from the pin'97, and

It has been hereinbefore" stated that the support for the work rest 20 is movable in guides 2 1 on the bed plate 10 so that a shoe may be readily placed upon the work rest when-the latter is in aforward position and sothat the work rest may be moved toward the rear of the machine to a position underthe driving head where it may receive a heel and top lift. To go more into detail in the construction of the work support which is completely. illustrated in Figs. 11 13 and 14:, it willbe'seen that the member 20v which somewhat resembles the form of a -last,i s attached to a head 105 mounted Thepost is vertically movable in its support 22 and is provided with a stud 106 which occupies alongitudinal slot 107 formed in the support. The stud 106 prevents rotation of the post 21 but permits longitudinal movement thereofwithin a limited range. The lower end of the post 21 is screw-threaded and engagedwitlr anut 108 contained. in the-base of the .jsup'port 22. By means of the nut 108, the post 21 may be raised or lowered andheld-inxany desired position relatively to the support 22. The head 105 is rigid with the post 21, and is provided with a transverse partially cylindrical boss 109 which occupies a corresponding partially cylindrical depression in the under side of the work rest 20. By means of so mounting the work rest on the head 105, the work rest is capable oftiltingrelatively to'the head s0 as to elevate more or less the heel or toe ,of a shoe supported thereon.

.sition, as shown by Figs. 2 may be readily placed thereon" and the whole The work rest is held in any desired position by adjusting means comprising a rod or stem 110 of which one end isspherical as indicated'at 111, and of which the other end is screw-threaded and adapted to receive a wrench by which it may be turned. The screw-threaded end of the stem extends transversely through a cylindrical nut 112 which is supported in the head 105 as on trunnions. The spherical end 111 is contained in a socket formed in the work rest 20 and confined therein by a plug 113. By means of the stem 110 having aball and socket connection with the work rest and pivoted screw-threaded connection withthe head 105, it may be seen that the work rest may be supported at. any desired inclination relatively to the head.

WVhenthe work rest is inits forward poand'3, a shoe may be moved manually to a position under the driving head. A suitable stop or work gage for determining the position of the shoe relatively to the driving head is illustrated in detail in Figs. 12, 15 and 16. For convenience, the work gage may consist of a fixedlsupport 120 secured to the bed'plate 10 and having a relatively fixed stop'121 adapted to'limit the rearward movement of a shoe, and ooeperative clamps adapted to receive the shoe between them and clamp it firmlyupon the work support as shown in Fig. '4. The stop 121 is preferably adjustable toward and from the bed plate 10 and toward and from the work rest. For this purpose the stop is clamped by means of a bolt122 to a head-123 formed on one end of a shaft 124C longitudinally movable in the free to move longitudinally in its socket and it prevents the shaft 12% fromturning in its bearing in the fixed support. The support is provided with an adjusting screw 12? mounted in a bearing at its rear end and provided. with a hand wheel 128. The screw-12,7 is so mounted that it may be freely turned by means of the hand wheel, but isincapable of longitudinal movement. By means of the screw 127, the shaft 124 may be adjusted longitudinally in its bearing in the support 120 to desired position. The bolt 122 which clamps the stop 121 to the head 123 extends through a vertical slot129 formed in the stop. A tongue 130 is also formed onthe stop 121 and cocupies a vertical groove 131 formed in the head 123. By reason. of the slot 129,.the stop 121 may be raised or lowered relatively to the head 123 when .thebolt 122 is released, and when the bolt is set up so as to clamp, the stop 121 with its tongue 130 in driving head one downward and an upward stroke each time the treadle. is depressed.

the groove 131, thestop is held rigidly against all movement.

132 132 are a pair of arms .pivoted at 133 to the lower portion of the stop., The upper ends of the arms 132 are adapted to lie on the opposite sides of a shoe and they are provided with spring clips 13 1 13 iv which engage the sides of the shoe and clamp the sameupon the work rest so as to firmly hold the shoe in position during the operation of attaching a heel and lift. The spring clips 13 1 13 1 are afiixed to plates135. which have laterally extending slots 136 through for .the samepurposey'lhe arms 132 are provided with'swiveled blocks 138 which are screw-threaded to receive. independently movable hand screws 139. The hand screws extend toward each other and into the stop 121. The innerend of each hand screw is provided with a ball 14:0 aifixed to it, the two alls occupying an elongated aperture 141 formed in the stop which holds them to gether so that they abut'against each other. By this means either or both of the arms 132, may be individually adjusted so as to effect practically the same result as an adjustment of either of the plates 135. As indicated in Figs. 4 and 16, the spring clips 134 are so arranged that when a shoe mounted onthe work rest is moved rearwardly to o erative position, the heel of the shoe enters etween the clips thereby spreading them, and finally abuts against the stop 121. 1

All of the details of the invention have been described and their operations explained separately, and it .istherefore thought unnecessaryto set forth the complete operation of the machine as the latter can be readily understood by following the detailed descriptions. In practice, a inachine of this. character is provided with means preferably. a treadle by which a continuously rotating shaft or some equivalent mayibecontrolled so as to impart to the The operation of removing a shoe from the workrest and placingv a new one thereon requires a pause of such duration that an attendant at thef'rea'r of the machine has ample time in which to supply a loaded heel to one of the heel carriers and a lift to one of the lift carriers. ,Then when a new shoe has been placed in operative posi tion and the treadledepressed onceso as to effect-the attachment of the heel, the operator may immediately epre s the treadle again. so as to efi'ect the attachment ofa lift tothe previously attached heel. It therefore follows that there need notbeanyprolonged pause between the attachment of a heel and the attachment of a lift, but that the longer space of time required for removing one shoe and inserting another may be utilized by the attendant at the rear of the machine in supplying a heel andlift as described.
